  1. Hi everyone Cheepo refractor, with an attempt at HOO. The filter reflects a lot of light, so we used 8 minute frames. Even so, it still doesn't look much like. Indeed, a broken heart. Thanks for looking and do post your dslr heart images. eos700d @ iso800 calibración: Siril procesado: StarTools 1.8.516 A NBAccent
  2. Excellent job. Suggestion. Fit an m5 nut and then three more springs to the locking screws; 6 springs in total. Cheers
  3. Exactly as recommended. Do nothing in Siril apart from calibrate and stack.
  4. Hi To make sure you have your data in the best shape possible (we need every gram we can muster) be sure to read the dataset preparation detail. Cheers and good luck
  5. Hi Very nice detail. Well done. Strange. That shouldn't happen. Did you do anything to the data before you loaded into st? Maybe have a look through the dataset dos and donts? Post a -link to- the data if you like. Cheers
  6. That's how I find it. I'm happy to change it to whatever you like. As you have said several times, in ps it's essential to set the background before proceding. Get that wrong and there's no hope. I agree. I'm not happy with that approach. It doesn't work for me and it takes ages. If it works for you though, great:) Cheers
  7. Hi everyone. Thanks to flo and to all who posted. Lovely detail. StarTools 1.8.512 with S in NBAccents. Thanks for looking.
  8. No need to be. On a superficial level, have a look at the StarTools app -there's only one screen- and see if you can find anything to do with levels/curves. I placed a link here which may help further. If not, I'm certain that @jager945could fill you in on what's what far better than my level of technical english will allow;) I think it good that alternative methods of processing images are emerging. Of course, if you're happier with curves and masks, just stick with it. Cheers and HTH
  9. There's quite a good 're-sample' under 'Geometry' but it seems to lose the faint bits which StarTools' 'Bin' retains. What we haven't tried is a Siril re-sample followed by subsequent processing in StarTools. Maybe then, the outcome would be similar... ?
  10. Hi There's a tutorial for those upgrading/migrating from PI to StarTools here. HTH
  11. Hi. You need to begin with an extra 10mm of spacing to give around 65mm, shoulder of the adapter to sensor. That works for aps-c but we've no experience of full frame with the big ES. Maybe a starting point though? IIRC, Bresser told us 'anywhere between 65 and 70'. HTH
  12. Hi Banding. Hands on with a selection of 24mp eos': some do, some don't. If you want to be certain, all the 18mp sensors we've tried are clean. 600d, 700d, 4000d etc. HTH
  13. Don't know them but looking at your images, I'd stay right where you are:) We allowed out trial of pi to expire. The calibration and stacking part of it is good but this is now more than adequately covered by Siril, which is open-source. Beyond that it, like ps, is just another collection of unrelated stretch-and-hope modules largely unchanged since the 19-nineties. These days, there are alternatives. +1 Linear data throughout.. No irreversible stretching. No levels or curves. No all-nighters. YOU decide how deep you want to go... A relief. Maybe the best way to decide though would be to take your data along to an astro club and see the alternatives being used first hand. Working in isolation with Internet and YouTube is perhaps not the best way to get going with new stuff. Just our €0.02 but HTH anyway.
  14. It will help guide DEC without it having to reverse direction.
  15. Hi - Look at the numbers if and only if the images from your main camera are not to your satisfaction. - Adjust polar alignment to around 5' error. Cheers
  16. Do Aliexpress do UK? To Spain, this seller ships from Europe. Just specify Europe and the size you want at the checkout.
  17. Hi As you'll lose the ability to reproduce natural colour with the CLS anyway, how about a UHC? We prefer the latter to the -much more expensive- duo band filters. It gives a similar if not almost identical effect to the latter. The 2" version is more economical and does the same job. HTH
  18. The pds springs are rubbish! We'd recommend replacing them with longer 1.6mm wire versions. 6 off, distributed 3 over the existing adjusters and a further three 'passive' over the lock screws. Collimation will then hold both between sessions and at any tube angle without having to resort (hehe!) to the locking action. Cheers
  19. +1 But much improved already. It looks as though you have the focuser protruding too: 'D' shaped stars. 10mm or so cut from the end should do it. Getting there:) Cheers
  20. if you're happy with what you have and have the time to spend with it, then absolutely no need to change. But as you'd isolated your main issue, I thought I'd point out that these days, FWOABW 'the point of no return' really can be effectively avoided. cheers
  21. Hi For precisely this reason, we gladly allowed our pi trial to expire. Removing the distinction between linear and non-linear data by moving to StarTools was a breath of fresh air. Of course the dark art remains, but is far more under your control. In the end I suppose it's with what you're most familiar which counts. Oh, and lovely pelicans:) Cheers
  22. +1 Get a proper adjustable eos-m42 adapter. Tighten the inner ring under gravity with the lens pushing down upon it. On our Tair 3s, take focus until the red halo predominates then back the other way tiny amounts until the red ring JUST disappears. Now tape the focus wheel securely. Use the click stop at f5.6. HTH
  23. The rogue pixels are found at fixed positions on the camera sensor. Each group of 25 points is produced by the same hot pixel. Due to the dither, aligning the stars in each frame prior to stacking causes the pixel to appear to move. Of course, it remains at exactly the same coordinates on the camera's sensor.
  24. Similar to AutoDev, but used mainly for combining narrowband data with RGB data. No more jumping through hoops trying to merge Ha with red etc... Details here. Cheers
